IMPROVEMENT IN WATER-CLOSET VALVES.

Specification forming part of Letters Patent No. 209,345, dated October29, 1878 application filed June 17, 1878.

To all whom it may concern:

Be it known that 1, JAMES P. KENYON, of the city of Brooklyn, in thecounty of Kings and State of New York, have invented a new and usefulImprovement in Automatic Valves for ater-Closets, which improvement isfully set forth in the following specification, reference-being had tothe accompanying drawings.

The subscriber has sought in this invention to obviate a number ofdefects and inconveniences complained of in the make-up and use ofrelated articles in this important sanitary department, and to produce avalve, first,

is weak and the flow languid thirdly, in which there is no diaphragm,and yet which cannot leak externally, even after a considerable amountof internal wear; fonrthly, in which no water shall waste till thecleansing-flow ceases; fifthly, in which the closing-check device isself-clearing at every stroke of the plunger; sixthly, in which thepartial flow necessary before the cleansing-flow commences is determinedand adapted to various pressures by a positive device unchanging in itsaction.

The devices by which these objects are accomplished are shown in Figure1, which is a vertical section through the middle of the shell and theinduction and eduction ports, in which a is the cylinder or shell of thevalve; 1), the cap; 0, the tube to receive the lower end of a rod; d,the flange, through which four fastening-screws pass; 6, theinduction-port; f, the eduction-port and g, the wasteway, which must beunderstood to be at right angles with the ports. The shell 0. is beveledout at its top to admit'of the easy entrance of the leather cups,whilethe internal diameter of its lower end is contracted, as shown, inorder that the inverted cup 0", during withdrawal, may pass with freedomthe tops of the ports.

Fig. 2 shows the induction-port e, as seen from the inside of thecylinder, a little deeper than the stroke, to allow the receding waterin the last part of the downstroke to get back through the port; Fig. 8,the eduction-portf,

widened at the cylinder, and narrowing and terminating in a round portas it extends outward; Fig. 4, a top view of the puppet-valve seat,showing the fissure therein.

The plunger is composed as follows: Three cups, of leather or othersuitable material, as shown at o o 0"; the spindle h, threaded at itstop and shouldered midway of its length, with a flange at its lower end,all as shown; the ch oke-fl an ge i, resting on the shoulder of h andtightened on 0 by the spindlethread entering c; a jam-nut, j, flanged,as shown, as a support for 0; a cylinder, is, crossed, as shown, by asolid partition near the middle of its length;

l, a hollow and flanged nut, with a very. small fissure across one sideof its upper face, which furnishes a seat for the puppet-valve andaccommodation for a spring below, the space in which the puppet moperates being connected with the pressure by the hole in k at m. Six-,sided holds for a wrench are provided on 1),

and I, while the latter has a recess in the upper part'of its cavity totake the top coil of a spring (where one may be needed) and secure itswithdrawal with the plunger.

In making up the plunger, first slip or screw 0 onto j, then drop thelatter onto h; screw j into 70, then drop 7: onto h, followed by 0, and

' screw h into 0,- attach cup 0 as shown, drop puppet into nut Z, andscrew Z into k,- drop plunger into cylinder, and screw on cap 0.

The valve is shown in a state of rest. When the weight is applied theplunger descends to a free flow for the final cleansing. The nextmotion'carries the plunger to a point'at which 0 cuts off the flow. Thisand the third motion, which latter completes the upstroke, are slow,regulated by the rate at which the space un der 1 can fill through thefissure in the puppetseat. During the early part of this slow motionthere is ample time for all the water above 0 to run ofi before thewasteway is covered by that cup, so that no ordinary leak can everappear externally. Even should a little water leak past 0 during therest of its upward motion, there is ample room for it in the spacearound the bottom of 0 till the next downstroke. In this upward movementof the plunger, 0 cutsoif the flow just as the lower edge of 0 reachesthe bottom of the wasteway, so that no water is wasted save that whichfills the pipe leading from the eduction-port to the bowl. When 0 hasfully closed the inlet and o has passed the bottom of the wasteway(while the upstroke is quietly continuing) the water begins to descendfrom the pipe just mentioned into the space between t and j, and thencepasses through the perforation in t and around the circumference of thelatter to the wasteway. While 01 covers the ednction-port, itoverlapsequally the top and bottom of that opening, and permits the passage of just so much Water (according to its diameter and the pressure) as willkeep the bowl wet and prevent the too tenacious adhesion of more solidmatter.

The closing device in this valve had to be different from that of anyother known to the present applicant. There is so little space below Ito be filled that a puncture in that part could not be made small enoughto allow sufficient time for the flow, not to mention the liability ofsuch an aperture to frequent choking. A spring being equally out of thequestion, except as an assistance to weak pressures, the combination ofthe present device was prev ferred, as in every downstroke of theplunger the refluent water'will lift the puppet and form a kind ofcoronal swash around the head of I,

removing any particle that might have interposed itself at the previousclosure.

Having fully described the construction and operation of my improvedValve, I claim as new, and desire to secure by Letters Patent, thefollowing:

1. In combination with the cylinder a, provided with induction andeduction ports and a wasteway, as shown, the plunger, substantiall y asdescribed, consisting of two main portions, each having a distinctfunction and a measurably independent action, as explained, said mainportions being connected or swiveled together by the spindle h, all forthe purposes set forth.

2. In combination with the cylinder and plunger aforesaid, theinductioirport an d wasteway, so arranged in relation to the traverse of0 and 0 as to prevent external leakage and the loss of any water savethat intended to be used, as specified.

3. In combination with a plunger and cylinder, constructed and arrangedsubstantially as shown, the chokeflange t, to permit and regulate apartial flow, as explained.

4. In combination with the cylinder and plunger, the nut 1, providedwith a small fissure across its face, and puppet .r, to regulate thefilling of the space below the nut, substantially as described.
